Phenotypes of a mutant
inactivation of ''[gene|5872812AB61E92E2944E926915EB7FEE71BFA6D5|abh]'' results in sensitivity against beta-lactam antibiotics that can be restored by induction of ''[gene|920F91E748EE079FF864011D9052B073567C41E4|slrR]'' expression or by inactivation of the genes encoding major autolysins (''[gene|6A21293823151C6980BF52B31A4B249A8440F2E1|lytC], [gene|E8B88CBE4F9121DFEEF099D7947CD1E1AE656160|lytF]'') [Pubmed|22211522]
